Yoo Jae Suk talked about his newborn daughter. 

On the April 8 airing of KBS Cool FM's 'Yoon Jung Soo and Nam Chang Hee's Mr. Radio,' Yoo Jae Suk made an audio appearance over the phone. 

One listener sent in a unique question, asking Yoo Jae Suk about his favorite smell. He replied, "That's a very unexpected question," and said, "The smell I love the most now is the smell of my baby when I hold her in my arms."

Back in October, Yoo Jae Suk and Na Kyung Eun welcomed their second baby.
